  "description": "In the Linux kernel, the following vulnerability has been resolved:  ubifs: Fix memleak when insert_old_idx() failed  Following process will cause a memleak for copied up znode:  dirty_cow_znode   zn = copy_znode(c, znode);   err = insert_old_idx(c, zbr-\u003Elnum, zbr-\u003Eoffs);   if (unlikely(err))      return ERR_PTR(err);   // No one refers to zn.  Fetch a reproducer in [Link].  Function copy_znode() is split into 2 parts: resource allocation and znode replacement, insert_old_idx() is split in similar way, so resource cleanup could be done in error handling path without corrupting metadata(mem \u0026 disk). It\u0027s okay that old index inserting is put behind of add_idx_dirt(), old index is used in layout_leb_in_gaps(), so the two processes do not depend on each other.",
